When comparing Segoe UI Mono vs Fira Code, the Slant community recommends Fira Code for most people. In the question“What are the best programming fonts?” Fira Code is ranked 5th while Segoe UI Mono is ranked 36th. The most important reason people chose Fira Code is:
This is particularly beneficial for those who wish to use combined letters such as "æ" and other diphthongs. But when it comes to programming, the ability to scan through your code is improved with ligatures for equality, arrow functions, and more.
Ranked in these QuestionsQuestion Ranking

Segoe UI Mono is a very readable font.
Pro Has ligatures
Pro Good editor support
A list of supported editors and terminals can be found here.
Pro Supports retina displays
Fira Coda supports high pixel density retina displays.
Pro Frequent updates
The repository is frequently updated.
Pro Installs easily on Mac
Many ligature fonts on Github aren't "mac ready". This font comes pre-compiled and ready to install on Windows, Mac, and Linux.
Con The zero is not slashed
The zero is not slashed, which causes some problems when scanning source code. This is not an issue when the IDE supports coloring (like all major modern IDE's), but still there are instances where this is not the case. A primary example are T4 templates, where Microsoft has not yet provided coloring support.
Con Ligatures are nice-looking but harm clarity
Even though the font combines characters into ligatures, you still need to type the normal characters, and the ligatures make that difficult in many cases.
Con Dotted zero is less readable than slashed zero
FiraCode uses dotted zero instead of slashed zero which is less readable.
Con Needs support for ligatures
It can't work in plain terminal, must have built in support for ligatures in editor
Con No Sublime Text support
Not the font's fault but even the latest Sublime Text builds (e.g. 3126) don't support ligatures.
